I think some cats are just prone to anxiety and it's not surprising yours is, Em, after her start to life. Our cat was never happy in the 6 years we lived in Bristol, probably because there were lots of cats in the area. She rarely went outside and peed on the sitting room window and curtains any chance she had. We tried everything, including Feliway, plug-ins, tinfoil and cling film on the window sill, but nothing worked, apart from locking her out of the room at our bedtime. Even then, we still had to wash the curtains on average once a week for years, until we moved house. Thankfully, she liked the new house!
Spendy day, but got lots of stuff we'd run out of in town and paid the man who cuts the grass. £69.22 in total.
Glad to hear of some progress, Collie. Enjoy your ale.
